Document Type and Number:
WIPO Patent Application WO/2019/138065
Kind Code:
A1
Abstract:
The aim of the invention is to reduce corrosion of the pipes in particular in sulphuric acid production. This aim is achieved, according to the invention, by means of a tubular heat exchanger (1) in which the arrangement of the tubes (20) in the tube bundle (2) defines a tube area, which has a tube-free channel (23) between the outer edge of the tube bundle (2) and the lateral surface (41) thereof, wherein a protective plate (5) is arranged between the tube bundle (2) and the lateral surface (41), covering the tube bundle (2) parallel to the longitudinal axis (43), at least in the region which is opposite the inlet opening (13), and wherein the tube area has at least one empty space (6) which divides the tube bundle (2) in a direction substantially perpendicular to the longitudinal axis (43), wherein an empty space (6) is positioned in particular between the protective plate (5) and the longitudinal axis (43).
